![]() Several approaches can be employed to repair a retinal detachment: The goal of treatment is to re-attach the retina to the back wall of the eye and seal the tears or holes that caused the retinal detachment. Previous eye surgery such as cataract surgery.Family history of retinal tears or retinal detachment.Lattice degeneration (thinning in the peripheral retina, or the area outside of the central retina.).Risk factors for developing a rhegmatogenous retinal detachment include This type of retinal detachment is much less common and can occur in eyes with abnormal inflammation or excessive leakage from abnormal blood vessels. Exudative (ex OO day tive) retinal detachments form when fluid leaks out of blood vessels and accumulates under the retina.This type of retinal detachment may occur from diabetes or other conditions. Tractional retinal detachments are caused by scar tissue that grows on the surface of the retina and pulls the retina off the back wall of the eye.Retinal tears can develop when the vitreous gel separates from the retina as part of aging or in patients with abnormal thinning in the peripheral retina (known as lattice degeneration) or occasionally from trauma. They are caused by a hole or tear in the retina that allows fluid to pass through and collect underneath the retina, detaching it from its underlying blood supply. Rhegmatogenous (reg ma TODGE uh nus) retinal detachments are the most common type.In general, retinal detachments can be categorized based on the cause of the detachment: rhegmatogenous, tractional, or exudative. The severity of the symptoms is often related to the extent of the detachment. In other cases of retinal detachment, patients may not be aware of any changes in their vision. Vitrectomy is an operation to remove the gel from the inside of the eyeball, and forcing the retina to reattach from the inside of the eye.When the retina is detached from the back wall of the eye, it is separated from its blood supply and no longer functions properly. The typical symptoms of a retinal detachment include floaters, flashing lights, and a shadow or curtain in the peripheral (noncentral) vision that can be stationary (non-moving) or progress toward, and involve, the center of vision. If scleral buckle is not successful or if the detachment is more complex,** vitrectomy may be necessary. The success rate of scleral buckle is in the upper 90s%. This enables the detached retina to stick to it more easily, especially after the fluid under the detached retina is removed (by perforating the eyeball from the outside with a tiny hole (in essence it is like pushing in the wall to reattach to the separated wallpaper). The buckle is a small piece of silicone that is attached to the outside of the eyeball to force it inwards. The standard operation to reattach the retina is a scleral buckle, perhaps better termed scleral indentation, because in this operation, the entire wall of the eye is pushed inwards to touch the detached wallpaper. Treatment involves identifying where the tears or holes are in the retina, then sealing these off and allowing the retina to reattach. With age, it turns to liquid, (patients note floaters at this stage) 2) the partly liquid gel may separate from the retina at some point in life (patients notice flashing lights when this happens), and this can sometimes cause a tear or hole in the retina 3) fluid in the vitreous passes through the tear and accumulates under the retina, causing it to detach from the wall of the eye, (patients notice a curtain over part of their vision when this happens). In a child, this gel is like a cast of jello. Retinal detachments happen because: 1) the gel in the middle of the eye, called “vitreous,” is partly stuck to the retina, which is the wallpaper of the eye. The classic symptoms of RD are floaters, flashes, and blurred vision, often described as a ‘curtain’ over the field of vision. Trauma can sometimes cause RD as well (less than 2% of the time). Retinal Detachment (RD) due to retinal holes or tears (rhegmatogenous retina detachment) occurs in approximately 1:10,000 in the general population, but is more common in near-sighted (myopic) individuals and after cataract surgery. Typical retinal detachment surgeries are scleral buckle and/or vitrectomy.This problem requires treatment, usually surgery.“Detachment” is the term used when the wallpaper comes off of the wall.The “retina” is like the wallpaper on the inside of the eye. ![]()
